I see stuff along the lines of:

  if (x == 0) {
      return y;
  }
  
  y += 25*x;
  return y;
and skipping the if just makes the function shorter and simpler, while also not involving the CPU branch prediction. Another one that doesn't necessarily skip all branching but at least drops one - and more importantly makes the code simpler and easy to verify, is removing the if statement in code like

  if (count == 0) {
      return;
  }

  for (int i = 0; i != count; i++) {
    puts("hello");
  }
